Help!!   How can I get maple 14's fonts to be smoothed?  In Windows it seems to pick up the OS setting on smoothing fonts, but not under K/ubuntu 10.10

HELP!!!!!!!!!!!!!

Hi I have just begun to use Maple and there are some function I am not able to use.I have 3 questions

1. I would like to plot the normal function (given a specific expected value and variance): is there a simple function to do it or I just have to re-write the function inside Maple?
2. is it possible to draw a line for a specific value of the graph, let's say x=1 without drawing an entire line for the graph (just to highlight the point)
3. is it possible...

Hi,

Currently I have to deal with this nonlinear differential equations. The "Newton iteration is not converging" is the main problem. Could anyone propose some solutions?

Thanks a lot.

Hello,

I use the following commands to generate the frequency response of a system,

with(DynamicSystems):

sys := TransferFunction(10/(s*(s+1)*((1/4)*s^2+1))):

NyquistPlot(sys)

but the figure which maple outputs seems not good because the ranges of x-y axises are very large. I try to use NyquistPlot(sys,view=[-20..20,-20..20...

Hey Mapleprimes,

 I have a set of 3x4 Matrices and i need to filter some out, but cant find the right maple commands. Example Matrix:

[2 4 0]    row 1

[0 2 2]    row 2

[0 2 2]    row 3

[4 4 4]

row 2 = row 3

1. If all elements of a matrix have a common divider, such as 2 in the example matrix, I need to store the simplified matrix, meaning the one with all values divided by the common divider....

I am setting up a new machine.

I was running Maple 13 on another machine running Fedora Linux 13.   I don't remember if I had any problems setting it up, but it was running fine.

But I removed it from the old machine and installed it on the new machine which is running Fedora 14 Linux.

Maple 13 loads but I get a message from SELInux about a problem with Maples's mserver and execcstack.   ...

I have problems with a variable that is given only implicitly. Maple provides incorrect answers but I am not sure where I make the mistake. Thanks for any comments! Here is what I do:

(1) I use "assume" to set properties of two paramters a and b.

> assume(a > 1);
> assume(b > 1);

(2) Since the variable "x" is given only implicitly, I define an implicit function following the description in the thread "How to define an implicit function in Maple?".

Hi, i want to overload the operators of union, intersection etc. But i do not know how to start this. kindly provide basic help. thanks.

Here is the info that i have i need to plot a piecewise-defined funtion that has a value sin(x) between -2*Pi and -1, value x-1 between -1 and 2, and a value of cos(x) for x between 2 and 5. Can anyone help me?

Hello,

After using the following command

print(plots:-display(%,%%)):

I generate a graphic. This graphic is possible to export as JPEG format using the mouse (selecting the option to "export").

Nevertheless, I would like to export (in JPEG format) this graphic (plot) using commands of Maple. How could I do that?

Thanks a lot for your attention,

Jean-Jacques

I am attempting to create an interactive number line.  I would like to allow the user plot a point on the number line with the mouse.  The value of the point plotted would be passed back to a Java program.  Can Maple do this? What is the best way to implement this?  

Thanks
